Why the Stock’s Still Heavy
MSTR’s equity typically amplifies Bitcoin’s direction because BTC dominates its balance sheet. When spot weakens, and macro risk appetite fades, that embedded “BTC beta” pulls the stock lower, even during aggressive accumulation streaks. Barron’s also notes BTC has shed more than 30% since its October peak, weighing on sentiment toward the whole crypto-proxy complex.
Despite that, Strategy keeps buying. 10,645 BTC this past week alone brings its stash to 671,268 BTC. But with Bitcoin near $90K and risk appetite shaky, MSTR remains under pressure, underscoring how tightly the stock’s fortunes are tied to the coin’s next move.
